- Abstract
The menstrual cycle (MC) is primarily responsible for changes in female physiology. The aim of this study was to assess the influence of different phases of the MC on resting heart rate (RHR) in healthy women with and without the use of oral contraceptive. Forty-four university women with age range from 18 to 35 yrs were divided into two groups. The Control Group (CG) who were oral contraceptive users (n=24) and the Experimental Group (EG) who were not contraceptive users (n=20). The participants made three visits to the laboratory; one in each phase of the cycle (follicular, ovulatory, and luteal). The RHR was evaluated during a 10-min period in the supine position, and was considered the lowest value recorded by the heart rate monitor. No significant differences (P>0.05) were obtained between the three phases of the MC within-groups and between-groups. The results suggest that the different phases of the MC did not alter the RHR in healthy university women independently of the use of oral contraceptive.
